So one night I started getting a random break up at WOT. What parameters should I be data logging to check this? Hardware i have is an SCT xcal 3 and live link. I also have a wideband.
I tried data logging using the Ford misfire PID in live link and got some odd results. For example the picture below will show a spike. That value though isn't a basic "1" it shoots to like 54k for a split second and returns to normal. However that value changes. Sometimes it's half that or less.
On a data log wot pull I have everything seems good except for the rpm. You can see each dip when the car breaks up. I'll post a picture of that too. No change in stft, ltft or spark, timing nothing just a normal good looking data log. I have noticed my wideband going lean to a value of 1 lamba on these instances. Normal WOT shows .84ish lamba which is good just those small blips. (Wide band is on driver side after LT collector)
Any thoughts or help.
